Script to record camera every 15 minutes

I have 2 cameras (AMCREST IP2M-841EW). I can currently view the camera feed from a browser. I need to make a script for both the cameras which will do the following: 1) User presses a button like F6. 2) Both cameras begin recording for 15 minute intervals. 3) After 15 minutes, video is stored in a folder and the camera records again. 4) Once user presses F6 to stop, the cameras stop recording. You'll find people who tried to implement some scripts on Google which you could use as inspiration. (I'll post some examples which may or may not help) [login to view URL] https://s3.amazonaws.com/amcrest-files/Amcrest+HTTP+API+[login to view URL] [login to view URL]
